how to solve kmap

whenever you see this kind of pattern, i think you can assume that it is the xor function. 1 way to solve it is to get the function and simplify it manually, i think we cant get the answer straight away from the kmap.

Solve using Kmap:

Manual simplification is not a good way to simplfy the function, since the it depends on your ability to see the common terms and even depend on your luck or your mood :D. So we must use procedural ways to do jobs.
It also saves time
